Two different issues:
G3-572, I installed w10 1809 on it and noticed ntoskrnl heating the pc while it is in idle. Is there some way to fix it?
I have other partition with 1803 installed without this problem, my main OS instance, btw. But, when I start some games on it, no matter which gpu I tell it to use, it have poor performance on laptop display... and when I plug an external monitor and play on it, performance is where it should. What can I do?
